I'm assuming if Adam buys his feeders from a good supplier, which I'm sure he does, they've been fed and watered recently. Why I suggest it is because a lot of members here buy from pet stores. Some pet stores are decent, some are horrible. I don't see why it's a problem to take time to make sure a creature has a meal and some water before you use it for a food item for your snake. We're not talking 500 mice/rats here, we're talking a person buying a few rodents a week. I don't have to do this, I raise my own but when I bought from pet stores, I did it because those rodents are often so overcrowded I can't imagine they've had much of a chance at the food supply or water bottle. I'd rather put in a hydrated, recently fed prey item.
